Blog: Favourite YouTube Videos (Volume 134)

In this volume of my favourite YouTube videos, we think about sex, wander a mountain and then fly off into the sky.

• First, from Sexplanations,  Dr. Lindsay Doe takes a look at how we figure out what sex we are.
• Next, Kristina Horner and Eia Waltzer show off their "Frozen" cosplay on a frozen mountain.
• Finally, Laura Shigihara lifts our spirits covering "Where No One Goes" from "How to Train Your Dragon 2".
